Another website may sell a headstone with a checkout button and a stock photo. This page describes how an order works here. It does not name another seller, and it does not invent that seller's price.
On this site a published listing shows the price stored for that design. The monument cost calculator repeats those stored prices as a planning estimate. It is not a second price list. Full custom does not have its own stored price. The exact price is confirmed on a design call.
Before the stone is cut, you review a proof. The return policy says the finished monument is guaranteed to match the proof you approved, and that a custom monument cannot be returned for a refund once fabrication has started. That is why the proof exists. An error that was on the approved proof is a modification. An error that was not on the proof is corrected by the shop.
Granite color is your choice. The granite colors page does not select a color for you. The product page shows the price stored for the color you pick when that color has a stored price.
We install nearby or ship free. Shipping to the lower 48 is included. A cemetery can still require its own foundation, its own setting crew, or its own fee. Those rules belong to the cemetery. Ask before you treat a listing price as the amount you will pay at the grave.
If you are comparing this site with another, compare the stone, the proof, what the price includes, and who sets the monument. A number from a page that is not this site is not a number this page can confirm.
